Public and private vehicle fleets have long been targeted as an ideal initial market for alternative fuel vehicles (AFVs). We examine seven widely accepted hypotheses regarding the potential fleet market for AFVs. The hypotheses are tested using data and information collected from focus group...

Population growth, continuing suburbanization, and higher labor-force-participation rates, combined with a virtual halt in new freeway construction, have led to rapid increases in traffic congestion in the U.S. This congestion is costly, for example, the cost of highway congestion in the Lose...

The substantial reductions in motor vehicle emissions that have occurred since the late 1960s have been accompanied by continuous increases in vehicle emission control costs, and cost increases or decreases due to changes in vehicle performance such as driveability, power, fuel economy, and...

High octane gasolines, including “premium†and midgrade, steadily gained market share in the United States during the 1980s, increasing from 12% of the total gasoline market in 1983 to 15% in 1985 and 30% in 1989. This 18% increase in market share represents an aggregate revenue...

Previous studies of the potential market for battery electric vehicles (BEVs) have reached contradictory conclusions. What they share are untested or implausible assumptions about consumer response to new transportation technology. We frame the BEV purchase decision in terms of a household's...

Analysts today would like to assess the emissions impacts likely to result from future implementation of intelligent vehicle and highway system (IVHS) concepts. This requires making assumptions about the simultaneous emergence of technologies and policies. Assumptions about emission...
